Abstract (en)
[origin: WO0046740A1] A method of non-linear and linear scale-up or scale-down image resolution conversion of digital images. The method is based on using non-linear or linear pixel position control functions relating an output image pixel grid to an input image pixel grid, where resolution of each grid is different. The pixel position control functions enable calculation of real pixel position coordinates of output image pixels, embedded within the input image grid. A connection grid is set up as a graphical representation of using the pixel position control functions.
